I do not have any specific information about a product called Nano Stone. However, in general, the frost resistance of a building material depends on its composition and density. Most natural stones, such as granite and slate, are considered frost resistant because of their low porosity and hardness. Man-made synthetic stones made from materials such as quartz and porcelain are also known for their frost resistance. It is important to check with the manufacturer or supplier for specific frost resistance ratings of a particular product.
